Thermal Runaway when OctoPi is connected, no issues otherwise

What is the problem?
Hi there.
When I try to print using OctoPi, I get a Thermal Runaway error and my print stops. This happens consistently with the same STL / Gecode files.

When printing directly from SD card on the printer without the OctoPi connected I do not get this error, and all my prints finish succesfully.

When observing the temperature logging in OctoPi I don't see any irregularities (spikes or drops) that would warrant an issue.

Printer Ender 3
Cura 4.1.0 Slicer

As a note, this is my first 3D printer and my first time using OctoPrint / OctoPi. I have been printing things directly from the SD card for 2/3 weeks without any issues like this.

What did you already try to solve it?
I tried several different slicer settings as I initially thought there was something wrong with those settings that may be causing this.

Tested the same gecode both from OctoPi and from SD card on Ender 3

No solutions for this? I'm now getting the same error on a CR10s Pro...

Hi!

Check your printer hardware that belong to the thermistors: Loose connection.

Also the logs would be quite handy.

I know this is an old post but did you ever solve this? I just set up my printer a week ago, been having a lot of fun with it. I got octoprint installed on a pi and hooked it up, and was still printing from an SD card and could monitor the print no issues. But so far, I've tried to print from Cura directly to Octoprint twice, and both times I get thermal runaways.

I still need to do some testing (printing from SD card again, printing from drag-and-drop gcode to octoprint, etc) to narrow it down.

Thanks,

Hello @Midnight_Tavern !

As this thread is not marked as Solved, it obviously has no solution.

If you need help, please open a new thread with all requested information.
This thread is way too old.

Understood. I know sometimes people who find solutions don't always come back and update things so I just wanted to check.

I will do a little more testing myself and then will open a new thread.
